Hi guys,
I have been reading through the forum trying to understand everything related to the T-Mobile locked LG G4.
I've got a few questions.
My story in short.
Got a brand new G4 H811VK shipped to me from LG instead of a bricked EU version of G4 I returned. The new phone is locked for T-Mobile, my own fault (they asked me what operator and I choose T-Mobile out of the blue). So this phone has never been on the T-Mobile network and I don't have an account with them.
I contacted T-Mobile and they said they couldn't help me and asked me to talk to LG. LG said they couldn't help me and asked me to talk to T-Mobile. I'm in the center of some loop with a completely locked and unusable phone (I'm in Europe btw.).
So my questions are:
1. Is there any known way to unlock my phone? (I tried swiftunlocks.com but it didn't work)
2. If no to no. 1, is there any other way I can use the phone? Flash a custom rom etc.
All help is greatly appreciated.
Thanks in advance and best regards,

am pretty sure you can unlock it but not sure wich place can do services for that.. for calls it must be sim unlock. even if you flash rom. search around in the internet you may find a place.

Hi,
I am new on the forum and i have been reading about unlocking the I-mate K-jam (WIZA200). I upgraded my ROM version a few days ago, and then my phone got "blacklisted" by my service provider last night. I have been using the phone for two months now, and i bought it from a second hand shop.
How do i unlock it so that it's not blacklisted anymore? I love the phone and can't afford to loose it.
Any help? I tried using Lokiwiz03a and it gave me 16 zeros as the lock status, and SIMLOCK code were just symbols.
Thanks alll

You will not be able to un-blacklist it with any tools here. The tools here are for unlocking or upgrading the unit. Blacklisting takes place at your provider. You will need to talk to them. Most likely it is blacklisted because it was stolen from its original owner. Is the second hand shop you bought it from reputable? It may be as simple as getting a new sim card from your provider, if your sim was just disabled. But if they banned the IMEI then you are most likely out of luck as far as using it as a phone. You should still be able to use it as a PDA though.

Hi, thanks for the advice. I tried the iwizard but will not work.my phone is a G4, so i need a different tool. It reads the IMEI and allows me to put in a new one, but does not change the IMEI after that, phone still shows the same one. i am changing it to that of my old phone (Motorola Mpx200) which i have to use now since my wizard is messed. Any other ideas? I am using the wizard love ROM and IPL/SPL 2.16.0001. Help????

If it's a G4 then completely forget about it. No solution exists!
The best to do is report the guy who sold you the phone or to sell it abroad since the blacklists are not shared internationaly

Thanks Mestrini. What about the software that imei-check.co.uk are selling? Would that work seeing that there is no free software existing?

No it wouldn't work because they do not want to (understandable from the company's point) and they even have a warning on their web about their products not being fit to change IMEI on handsets.

No, there is no solution available at the moment. A couple of people have been able to persuade ATT to give them codes after many days of phone calls and support chat. A few have had some varying success with turbo sims that supposedly fool the phone into thinking the sim is an ATT sim, but that's it.
based on what I have read online. ATT often will unlock your phone when you are in the contract for like 6 months or a year.
I called them with my tilt 2 about a year into my contract. Tell them that I am traveling oversea and want to use the phone internationally. They gave me the code without much hassle.
Not sure if this is partially due to the fact I have been with ATT for years.
Online search also shows that ATT will often unlock almost all smartphoen for you except iPhone, so keep try them and if the CSR does not help, ask for supervisor.

The official requirements are:
1. at least 90 days into a contract
2. Have a post paid account with contract
3. Paid all bills on time.

Captivate has proven to be an exception to this. There is already a long thread about Sim Unlock. The bottom line is AT&T won't give you a unlock code for Captivate until 10 months later.

If you're not an AT&T customer, they typically won't help you with unlock at all. Good luck.
Not sure why there is another unlock thread, but At&T told me they would. Unlock in 90 days. I have no reason to doubt them.

unlock Captivate with froyo
today i unlocked my captivate with an app called Galaxy S Unlock get it in the market very easy to do also on youtube i am running froyo 2.2, version I897ucji6 and i am rooted (need to be rooted)
Finally got the captivate to unlock and accept the tmobile sim today. Everything seems to be working fine so far. No data on the plan but using wifi til I add data. One thing I'm really curious about is.... Now that the phone is unlocked and working, If I flash a custom rom (say cognition for example) will I lose the "unlock" ?
*edit* forgot to say how I did it... I just simply flashed back to stock 2.1, master cleared,rooted, installed busybox and galaxy unlock app, used the #2 method with the unlock app and it worked. PATIENCE IS KEY! ===> It takes a good 2-4 minutes for the tmobile signal to kick in so it may seem as if the unlock failed but it just takes alot longer than the at&t signal to kick in.

All I did was call 611 and told them that I was leaving the country and I need it for business. However they have records that my previous phones have been unlocked for travels as well as me buying phone from them. You could always try and test your luck though. I've read a thread somewhere that someone got their S4A unlocked similar to how I got mine unlocked but they didn't specify whether or not they got it through AT&T or not. Oh and if it doesn't work with one rep, try calling again later with another rep. Supposedly some reps care and look into your records to see if you qualify and others don't give a crap. Good luck!
I have at&t and called them to try to get my phone unlocked. they told me it wasn't possible since I just purchased the phone back in August, even though I've had an account with them for the last decade and have had many unlocked phones with them.
I was told that this policy was changed within the last 2 weeks, not sure if that's a BS line they fed me or not, but have tried calling different reps and have had no luck.
Also, when I enter my number in online to the online request form, it automatically tells me my phone cannot be unlocked. Apparently new policy states that any phone that is still under contract will not be unlocked my AT&T.
where are all the helpful replies?
Im in the same boat. There has to b a way. Why cant we roll back the jellybean build to a version that has access to the unlock panel?
Why is unlocking not possible using a root method of some type??? Is this build truely not unlockable without a custom code? MOD Edit: This is a development site. Please do not ask for illegal unlocking methods here
post some links to helpful blogs etc please
This is the leading site for answers but mod says look elsewhere with no helpful redirection..... WTF?
Where should we go now then?

MOD kinda said they are a development site and don't partake in illegal methods. In case you didn't know, unlocking without carrier consent is illegal however rooting/flashing roms and etc aren't since they are just part of the opensource backbone of android. And to answer your question, google is a good place to start if you can't get answers here.
The reason the mods took issue with this is because the OP is not an AT$T customer, he bought a phone off eBay, and is now looking for someone to help him with his mistake. Carriers only unlock phones for customers as a courtesy, there is no requirement of them to do so. While XDA is all about modding phones, providing unlock codes for people who are not entitled to them is against their policy. Better that he bought one of the many unlocked phones for sale on eBay. I'm surprised the mods didn't also close this thread.
Look up Chainfires region lock away. Got a s4 active off eBay, rooted it with the activerootapp. Then used chainfires Regionlockaway. And popped in a tmobile sim card and enabled aws bands and now using HSPA+.

Ive never heard of sending a phone somewhere to be unlocked. Generally you either request an unlock code from your carrier or buy one from one of the many sim unlocking websites out there.
Have you contacted the place you sent your phone? That should be your first step. How much did it cost?

It was a cell phone store that usually repairs phones or unlocks them and so on, unfortunately I got out of T-Mobile too late to go back to the phone place. It cost $45 to unlock, and by seeing all these threads, I can already tell I overpaid.

Ouch! That's extortion! Unlock codes are usually around $5 from a third party site, or if the phone is off contract your carrier will give you the code for free. All you do is put in the new sim, type the code in the dialer and you're done. $45 for that is ridiculous. You definitely overpaid, sorry to say.
I saw in the other thread that some people had luck when they created a new APN. Have you tried that?

Yeah, I saw that, it was just my first time unlocking a phone and a friend had previously told me he got his unlocked there so I went there too. Never again, though. I did create a new APN and it connected to T-Mobile briefly for like 2 seconds before saying it had no service again. Now it doesn't connect at all. I don't think it has to do with it being unlocked wrong since other people have had the same problem. It definitely has something to do with the APN, I believe.
I had this problem and moto replaced my device. I still get disconnected from the new device but it's a lot better than the old one. I believe it's hardware issue. I'll have to call them again.

Hi guys
I recently bought a used 4xl off ebay that I want to install grapheneos on. I bought the tmobile variant to save some money, as I assumed as long as it wasnt the verizon variant the bootloader would be unlockable.
I've called 3 different tmobile support techs, and reached out to the @tmobilehelp twitter account, all of whom are saying the past owner has to call to have the phone sim unlocked. Is there a way to get the device unlocked without ever being a tmobile customer? I didn't originally have intentions to put a sim in the phone at all, but if i have to, i will.
What are my options to getting the bootloader/sim unlocked? Can I become a tmobile connect customer to get the phone on the network, and then request an unlock as i'd be the current owner of the phone?
Thanks

The past owner lost his phone or it was stolen while still under contract (hasn't been paid off), and it was sold on ebay. Pretty much the only option you have is to try and get your money back from the ebay vendor selling stolen phones. Have you contacted them already and what was their response? As for your last question about becoming a TMo customer with a stolen TMo phone, I guess you forgot to ask that when you talked with the 3 support techs? If you are lucky your IMEI is not blacklisted already and it is capable of being activated.
Hey!
I have a similar problem. Mine is from AT&T. The only thing you should know is if it is blacklisted or not.
If it is you may run into other problems!
I am still researching how to unlock the bootloader. I have already learned a lot of things but still trying... To get the phone unlocked I think the best way is to flash original firmware that comes with unlocked models(you can download it directly from google here )
Now, as the bootloader is locked, you can't just flash it directly as the bootloader won't allow you to flash things to certain partitions(like boot partition⛔️). I will let a pic of what you get, even if you use the force attribute.
The case is that Qualcomm chipsets have and especial mode called EDL.
With this mode you can flash any firmware, even if the bootloader is locked.
This is because the EDL is like the main bootloader, and then there is the 2 bootloader, which is the one is locked(See pic).
Concluding, what I am trying to do is flash the not locked firmware through the PBL(which you access through EDL mode, to get there just run "fastboot reboot edl" without quotes).
The problem is that you need some strange files, which appear to be very rare. They have an .mbn or .hex extension and I didn't find them yet. They are supposed to be inside the firmware, but I didn't find them yet.
When I finally find it, I am going to publish a full guide on how to unlock any firmware, even if it is from Verizon.
I already have understood how to unlock the phone to work with any SIM, mine despite being locked to AT&T it's working fine with my Vodafone SIM. Here is the link to my post
This information probably won't help because it's for a completely different device... But I had a OnePlus 6t prior to my Pixel 4XL and we had a T-Mobile to global conversion thread that used a tool that made our T-Mobile OnePlus 6t/6 a global model. I'll go grab the link to the thread and paste it here. I know OnePlus and Pixel are two completely different devices but what the hell. Hopefully it may help...
T-Mobile 6T to International Conversion (WITHOUT unlocked bootloader/SIM unlock!)
In the previous thread, we discussed a method to convert T-Mobile 6T's to the international variant, sort of, but it required an unlocked bootloader, which itself requires a SIM unlock which T-Mobile gives people a hard time about. However, it...
forum.xda-developers.com
That is more less what your aim is here in quite sure... Make your Pixel 4XL T-Mobile an unlocked model. It would seem like there would be some way to do it, unless whatever the OnePlus developers did to have the conversion work is a no go because of how the two devices are made. I'm not sure as I have not dug deep in to this just figured I'd share. When I read your post this is the first thing that came to my mind. I hope you get it resolved. All else fails sell the T-Mobile model and try and get a Google model Factory unlocked. They have come down even more now I'm pricing.. Anyway good luck man.
